Vitrified bond diamond grinding wheels for PCD tipped saw blade

Vitrified bond diamond grinding wheels are commonly used for precision grinding applications, including grinding PCD (Polycrystalline Diamond) tipped saw blades. PCD is a synthetic diamond material used in cutting tools due to its exceptional hardness and wear resistance.

Vitrified bond wheels are made by mixing diamond abrasive particles with a vitrified bond material, such as glass or ceramic. The mixture is then shaped into the desired wheel form and fired at high temperatures to create a solid bond. Vitrified bond wheels are known for their excellent cutting ability, high material removal rates, and long wheel life.

When grinding PCD tipped saw blades, vitrified bond diamond grinding wheels offer several advantages:

Hardness: Vitrified bond wheels are very hard and can withstand the high cutting forces and abrasive wear associated with grinding PCD. This ensures consistent grinding performance and dimensional accuracy.

Heat resistance: PCD grinding generates high heat due to its hardness and the nature of the cutting process. Vitrified bond wheels have good heat resistance, preventing excessive heat buildup and reducing the risk of thermal damage to the PCD tips.

Self-sharpening: Vitrified bond wheels have the ability to continuously expose fresh diamond abrasive particles during grinding. This self-sharpening characteristic helps maintain a sharp cutting edge and prolongs the wheel’s lifespan.

Precision and surface finish: Vitrified bond wheels provide excellent control over grinding precision, allowing for tight tolerances and smooth surface finishes on PCD saw blades.

When selecting a vitrified bond diamond grinding wheel for PCD tipped saw blade grinding, it is essential to consider factors such as wheel grit size, concentration, bond type, and wheel specifications, which should be compatible with the specific application requirements and machine parameters.

It’s worth noting that while vitrified bond diamond grinding wheels are widely used for PCD grinding, there are other bonding options available, such as resin bond and metal bond wheels. Each bond type offers unique characteristics and advantages, so it’s important to choose the most suitable option based on your specific needs.
